Oculopalatal tremor: Illustrative cases with a review of literature

Oculopalatal tremor (OPT) is a unique clinical sign characterized by involuntary movements of the soft palate in synchrony with ocular nystagmus, usually the pendular type. It is highly suggestive of and is a delayed complication of a brainstem lesion, often a stroke. The mechanism and clinical implications of OPT are still not fully elucidated and present a treatable complication of brainstem disease. We searched PubMed and Google Scholar for articles with keywords “Oculopalatal tremor.” Most relevant articles were reviewed, based on the number of citations and information was collated by both the authors. We present two cases of OPT which illustrate the clinical spectrum of OPT.
